  • the connecting devices 5 each have a busbar 2 .
  • each of the two housing shells 431, 432 has a recess 40 in which a printed circuit board 3 with the connection elements 1 fastened to it is mounted.
  • each of the connection devices 5, or each busbar 2 is assigned a connection element 1 in each case.
  • the printed circuit boards 3 are each mounted by pushing the connecting elements 1 onto the busbars 2 assigned to them.
  • pins 42 assigned to the connection elements 1 are provided as stop means, which are guided through through-holes 31 in the circuit board 3 .
  • the printed circuit board 3 placed in the first housing shell 431 is equipped with an electrical connection means 71
  • the printed circuit board 3 placed in the second housing shell 432 having a corresponding design Mating connection means 72 is equipped.
  • the connecting means 71 and counter-connecting means 72 are provided for the electrical connection of conductor tracks and/or conductive surfaces of the two printed circuit boards 3 . They are placed in such a way that they make electrically conductive contact when the housing shells 431, 432 are joined together. In order to make this possible, a breakout surface (not shown) is provided in the insulating wall 433, which is broken out before the terminal block 4 is mounted.
  • Figure 4(a) is an excerpt from the terminal block 4 of 3 shown.
  • the insulating wall 433 is not shown here.
  • connecting devices 5.1, 5.2 arranged opposite one another, which are designed as spring clamps. They each have a clamping cage 51.1, in which a clamping spring 52.1, 52.2 is arranged, with which an electrical conductor inserted into the connecting device 5.1, 5.2 can be clamped to a busbar 2.1, 2.2 assigned to the connecting device 5.1, 5.2, making electrical contact therewith.
  • an actuating means 53.1, 53.2 is provided in each case, which actuates the clamping spring 52.1, 52.2 by moving it so that it is adjusted against its restoring force and the clamping of the electrical conductor between the busbar 2.1, 2.2 and the clamping spring 52.1, 52.2 is repealed.
  • a connecting rail 20 is visible here, which electrically conductively connects the two busbars 2.1, 2.2 of the adjacent connecting devices 5.1, 5.2 to one another.
  • Figure 4(b) shows a housing shell 431 of a terminal block 4, which has a means 61 for snapping the terminal block 4 onto a rail (not shown).
  • a terminal block 4 which has a means 61 for snapping the terminal block 4 onto a rail (not shown).
